This is a gist that patches react-native's components and apis with jest to allow you to use Enzyme's react 16 adapter

Leave a comment if you are interested in this gist. If there is enough interest I'll take the time to keep adding to this and improve the mocks, mimicking the clipboard functionality for example.

I'm interested -- I've forked it in my own project.

great, thanks for sharing
